  • Abstract:
    In 2010, FHWA developed a new systematic, data-driven, risk-based oversight process for monitoring State compliance with the National Bridge Inspection Standards (NBIS). Based on the success of that process, FHWA has now developed a similar process for the recently implemented National Tunnel Inspection Standards (NTIS) required by 23 U.S.C. 144(h). This process utilizes 15 metrics, or measures, to define 1) the levels of compliance, 2) items from the NTIS to be measured, and 3) how those measurements affect the levels of compliance. Each metric can be traced directly to wording in 23 CFR 650 Subpart E. The metrics were developed over a 2-year period by a committee which consisted of FHWA Division, Resource Center, and Headquarters bridge and tunnel engineers. Refinements were made to the metrics based upon feedback received during development, including discussions based on pre-pilot evaluation of the metrics with a few States. In 2017, the FHWA initiated a pilot program using the new process in eight additional States. The FHWA made further adjustments to the process and the metrics following these pilots, in preparation for nationwide implementation in June 2019.
